Adobe Sign users are not able to contact support through the web portal.
During the handshake with Zendesk we pass on certain parameters to Zendesk but its lost when the app redirects back to our Sign application.
The param we are referring to is "shard=NA1_ES" (sample value).
The exact point at which the param is lost is when Zendesk redirects to below URL:
https://echosign.zendesk.com/hc/en-us/restricted?return_to=%2Fhc%2Fen-us
We believe that there is no allow-listing for any parameters with Zendesk and Zendesk will pass through any param that we send.
